Strange intermittent noise underneath vehicle

Asked by Apr 14, 2017 at 01:42 PM about the 2013 Ford Explorer XLT 4WD

Question type: Maintenance & Repair

I purchased a 2013 Explorer XLT last July and 3 months later, a strange
popping/rattling noise began one day...noise sounded like driving over fresh
asphalt paved highway with popping noise underneath. Shortly thereafter,
the popping noise stopped and a new noise, like a rattle, flapping, scraping
sound began and it continues even today. This noise is intermittent, with the
noise heard on driver's side, then it moves around the vehicle to rear and
back again to driver's side. It sounds almost like a metal scraping sound as
in the frame but 4 different garages and dealerships can't find anything

Check the catalytic convertor heat shields. They tend to rust at the welds and come loose. The popping noise might be some parts of the inside of the catalytic converters came loose and rattling around. The exhaust would need to be removed to check.

So grateful for your help. Your answer sounds the most likely of any I have heard yet. And this area of the vehicle has not been checked by any of the garages/dealerships I have dealt with.
